My Printer suddenly won't scan. Says "Computer not Listed"

[George8888]

I have a iMac running OS Sequoia 15.4. I have downloaded drivers and gone into HP Utility and enabled Computer, but it still doesn't register. Printing is okay. At a loss what to do since I have followed all the online suggestions.

Hi @George8888,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your printer!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

Verify Network Connection:

• Ensure your printer is connected to the same network as your iMac. You can check this through the printer's display menu under Network Settings.

Check HP Utility Settings:

• Open HP Utility on your computer and verify that your printer is selected.
• Ensure all necessary features are enabled, such as scan and fax capabilities.

Software Update:

• Confirm your macOS and printer software are up to date. You can check for updates through the App Store and ensure the latest HP drivers are installed.

Remove and Re-add Printer:

• Go to "System Preferences" > "Printers & Scanners."
• Remove the existing printer entry and re-add it by clicking the plus sign (+). Select your HP ENVY 5640 from the list to ensure proper registration.

Firewall and Security Settings:

• Check your Mac's firewall and security settings to ensure they are not blocking any printer communications.

Check for macOS Compatibility:

• Make sure that OS Sequoia 15.4 is supported by the HP driver files and scan software.

I hope this helps.
